The pair, who found love on ITV2's Love Island last year (17), have weathered their fair share of storms during their turbulent relationship. But now it has been claimed the couple have called time on their romance once and for all - although there are conflicting reports about how the split came about. Sources close to Olivia told The Sun that Chris ended things on the phone, before regretting his decision and asking for another chance - but that Olivia had decided by that point she was done. "Olivia has been pushed to the limit by Chris. She's spent months putting up with him and his bad behaviour," a source told the newspaper. "He ended it on the phone, but then begged Olivia to forgive him, as he has done before, but this time she has no interest." "She's done with him. She's stuck by him throughout everything - his feud with Katie Price and even the incident in the nightclub where he was seen appearing to kiss another woman, but she is fed up now and feels completely used by him. She's told him it's all over and that's it." News of the pair's split comes after Olivia hinted at trouble in a now deleted post on Twitter on Tuesday, in which she wrote: "I think one of the worst feelings in life is being angry at yourself. Angry for the way I tried to see the good in someone when no one else did. I fell for the lies. "I believed I was more then just a job (sic)." Meanwhile, sources close to Chris have insisted that it was Olivia sending flirty Twitter messages to her ex-boyfriend, footballer Bradley Dack, that led to Chris ending things with the model. "Olivia promised Chris that she no longer had contact with her ex and he continued to trust her on this," an insider explained to The Sun. "He is totally devastated and feels she has betrayed him. He has tried and tried to make it work, but can't carry on any more. He called her last week and ended things as it was clear they weren't making each other happy. He now just wants everyone to move on." Neither Chris nor Olivia have publicly responded to the split claims themselves.
